Why do you need to replace a bad sewer line?
Replacing a bad residential sewer line is important for several reasons:

  • Health and safety: A damaged sewer line can lead to the release of harmful bacteria, viruses, and other pathogens into your home and surrounding environment. This can pose a serious health risk to you and your family.

  • Property damage: A damaged sewer line can cause water damage and flooding in your home or property. Over time, this can lead to mold growth, structural damage, and other costly repairs.

  • Environmental impact: A damaged sewer line can also have a negative impact on the environment. Leaking sewage can contaminate nearby bodies of water, harming local wildlife and ecosystems.

  • Cost-effective: In some cases, repairing a damaged sewer line may be possible. However, if the damage is extensive, it may be more cost-effective in the long run to replace the entire line rather than constantly repairing it.

  • Improved functionality: A new sewer line will improve the functionality of your plumbing system, reducing the likelihood of clogs, backups, and other issues that can disrupt your daily life.

Overall, replacing a bad residential sewer line is a necessary step to ensure the health and safety of your family, protect your property, and maintain the integrity of the environment.

Is sewer pipe relining worth it?
Sewer pipe relining can be a cost-effective and practical solution for repairing damaged sewer pipes, depending on the extent of the damage and the condition of the existing pipe. Here are some of the advantages of sewer pipe relining:

  • Cost-effective: Sewer pipe relining can be less expensive than traditional pipe replacement methods since it doesn't require extensive excavation or removal of the old pipe.

  • Faster repair times: Since sewer pipe relining doesn't require excavation, it can often be completed in a shorter amount of time than traditional pipe replacement.

  • Durable and long-lasting: Many sewer pipe relining materials, such as epoxy resin, are durable and resistant to corrosion, ensuring a long-lasting repair.

  • Minimally disruptive: Since sewer pipe relining doesn't require excavation, it can minimize disruptions to your property and daily life.

However, sewer pipe relining may not be the best solution for all situations. In some cases, traditional pipe replacement may be necessary, especially if the damage is extensive or the existing pipe is too deteriorated to be relined effectively.

It's important to consult with us to determine the best course of action for your specific situation. They can assess the damage to your sewer line and recommend the most appropriate repair method, whether it's sewer pipe relining or traditional pipe replacement.

How do you install new sewer lines in an existing drain?
Installing new sewer lines in an existing drain typically involves one of two methods: open trench excavation or trenchless technology. Here's a brief overview of each method:

  • Open trench excavation: This involves digging a trench in the ground along the path of the new sewer line. The old pipe is removed, and the new pipe is installed in the trench. Once the new pipe is in place, the trench is backfilled and the surface is restored. This method is typically more invasive and can be more costly than trenchless technology, but it may be necessary in some situations.

  • Trenchless technology: This method involves inserting a new pipe into the existing drain using various techniques that do not require extensive excavation. There are several types of trenchless technology, including:

  • Pipe bursting: This method involves breaking the old pipe apart while simultaneously pulling a new pipe through the space left behind.

  • Cured-in-place-pipe (CIPP) lining: This involves inserting a flexible liner coated with epoxy resin into the old pipe and then curing it in place, creating a new pipe within the old one.

  • Slip lining: This involves inserting a smaller-diameter pipe into the old pipe and sealing it in place.

The specific method used will depend on several factors, including the condition of the existing pipe, the type of soil, and the accessibility of the sewer line. One of our licensed plumbers can assess your situation and recommend the most appropriate method for installing new sewer lines in your existing drain.

How do you fix a sagging sewer line?
We can fix a sagging sewer line by using one of several methods, depending on the severity of the sag and other factors. 

  • Pipe relining: This involves inserting a flexible liner coated with resin into the old pipe and curing it in place, creating a new pipe within the old one. The liner adheres to the interior of the old pipe and forms a seamless, jointless pipe that is structurally sound and resistant to corrosion.

  • Pipe bursting: This method involves breaking the old pipe apart while simultaneously pulling a new pipe through the space left behind. The old pipe is shattered and displaced into the surrounding soil, while the new pipe is installed in its place.

  • Excavation and replacement: In some cases, excavation may be necessary to replace the sagging section of the pipe with a new one. The old pipe is dug up and removed, and a new pipe is installed in its place.

Regardless of the repair method used, we will first inspect the sewer line using a camera to determine the extent of the sag and identify any other issues that may be contributing to the problem. We will then recommend the most appropriate repair method and perform the repair according to the specific procedure.

Fixing a sagging sewer line is a complex process that requires specialized equipment and expertise. If you suspect that you have a sagging sewer line, it's important to have it inspected to prevent further damage and potential health hazards.

Why does my main sewer line keep clogging up?
There can be several reasons why your main sewer line keeps clogging up. Here are some of the most common causes:

  • Tree roots: Tree roots can grow into the sewer line and cause blockages or even damage the pipes.

  • Flushing non-flushable items: Flushing non-flushable items like wipes, feminine hygiene products, and paper towels can cause blockages in the sewer line.

  • Accumulation of grease and fat: Grease and fat can accumulate in the sewer line over time and cause blockages.

  • Aging pipes: As sewer pipes age, they can become more susceptible to corrosion and damage, which can lead to blockages.

  • Poor installation: If the sewer line was not installed properly, it can lead to blockages and other issues.

  • Heavy rain or flooding: Heavy rain or flooding can cause debris and other materials to enter the sewer line, causing blockages.


How deep are sewer lines in Minnesota?
The depth of sewer lines in Minnesota can vary depending on a number of factors, including local building codes, soil conditions, and the type of sewer system in use. However, as a general rule, sewer lines in Minnesota are typically installed at a depth of at least 4 feet below ground level to protect them from freezing during the cold winter months. In some areas, sewer lines may be installed even deeper to ensure proper drainage and prevent damage from other underground utilities or excavation work. It's important to note that the exact depth of sewer lines can vary from one location to another, so if you need to know the specific depth of a sewer line on your property, it's best to consult with a licensed plumber or the local utility company.

How long do cast iron sewer pipes last?
Cast iron sewer pipes have a long lifespan, but their exact lifespan can vary depending on a number of factors, including the quality of the pipes, the environmental conditions they are exposed to, and how well they are maintained. Generally speaking, cast iron sewer pipes in Minnesota can last anywhere from 50 to 100 years or more before they need to be replaced.

Factors that can affect the lifespan of cast iron sewer pipes include the presence of corrosive materials in the soil, exposure to freezing and thawing cycles, and the amount of wear and tear the pipes are subjected to over time. Regular maintenance and repairs can help extend the lifespan of cast iron sewer pipes, but eventually they will need to be replaced as they begin to corrode or wear out.

What dissolves tree roots in sewer lines?
Copper sulfate is often used to dissolve tree roots in sewer lines. It is a chemical that is safe for sewer pipes and can effectively kill tree roots that have invaded the pipes. Copper sulfate works by creating a chemical reaction with the roots that causes them to break down and dissolve over time.

However, it's important to note that using copper sulfate to dissolve tree roots in sewer lines is not always a permanent solution. The roots may grow back over time and cause the same issue again, so it's important to address the underlying cause of the root invasion, such as a cracked or damaged pipe, to prevent future problems.

If you suspect that you have tree roots in your sewer line, it's best to have the issue inspected by one of our licensed plumbers so we can determine the extent of the problem and recommend the most appropriate solution, which may include using copper sulfate or other chemicals to kill the roots, repairing or replacing damaged pipes, or taking steps to prevent future root growth.

What does a bad sewer line look like?
A bad sewer line typically does not have any visible signs on the surface, as the sewer line is located underground. However, there are some indicators that can suggest a sewer line problem that may be visible:

  • Soggy spots in the yard: If you notice areas in your yard that are constantly wet or soggy, even during dry weather, it could be a sign of a leaking sewer line. The sewage leaking from the pipe can saturate the soil and cause the ground to become waterlogged.

  • Sinkholes or depressions: If you notice sinkholes or depressions forming in your yard, it could be a sign of a collapsing sewer line. As the ground gives way, it can create depressions or even sinkholes that could pose a safety hazard.

  • Unusual plant growth: If you notice an area of your yard where plants or grass seem to be growing much faster or greener than the surrounding area, it could be a sign of a leaking sewer line. The sewage leaking from the pipe can act as a fertilizer and stimulate plant growth.

It's important to note that these signs may not always be visible or may be difficult to spot. If you suspect that you have a bad sewer line, it's best to have the issue inspected by one of our licensed plumbers who can use specialized tools and techniques to locate and diagnose the problem.

What is the difference between a drain line and a sewer line?
A drain line and a sewer line are both types of pipes used for transporting wastewater from a building to a sewer or septic system, but they differ in some key ways.

A drain line is a pipe that carries wastewater away from individual plumbing fixtures, such as sinks, toilets, showers, and bathtubs. The drain line connects each fixture to a larger network of pipes that eventually leads to the main sewer line or septic tank. Drain lines are typically smaller in diameter than sewer lines and are designed to handle smaller volumes of water and waste.

A sewer line, on the other hand, is a pipe that carries wastewater from multiple drain lines and other sources, such as roof gutters and stormwater drains, to a municipal sewer system or a septic tank. Sewer lines are larger in diameter than drain lines and are designed to handle larger volumes of wastewater and solid waste.

In summary, drain lines are the pipes that connect individual plumbing fixtures to a larger network of pipes, while sewer lines are the larger pipes that transport wastewater from multiple sources to a municipal sewer system or septic tank.

How often do you need to clean your sewer line?
The frequency at which you need to clean your sewer line in Minnesota can vary depending on several factors, including the age of your home's plumbing system, the size of your household, and the types of materials that go down your drains.

In general, it is recommended to have your sewer line cleaned every 18 to 24 months as a preventive measure. However, if you notice any signs of a clog, such as slow drains or backups, you should have your sewer line inspected and cleaned as soon as possible.

Additionally, if you have a large household or a lot of trees on your property, you may need to have your sewer line cleaned more frequently. Tree roots can grow into sewer lines, causing blockages and damage, so if you have a lot of trees near your sewer line, it's a good idea to have it inspected and cleaned more often.

Ultimately, the best way to determine how often you need to clean your sewer line is to have it inspected by a licensed plumber. Metro Earthworks can assess the condition of your sewer line and recommend a cleaning schedule that is tailored to your specific needs.

Can a cracked clay sewer pipe be patched?
While it is possible to patch a cracked clay sewer pipe, it may not be the most effective solution in the long run. Clay pipes are prone to cracking and damage over time due to age, shifting soil, and other factors, and patching a crack may only be a temporary fix.In some cases, we’d recommend a long term fix by relining the damaged pipe with a new pipe lining. This involves inserting a flexible liner into the existing pipe and then inflating it to mold it to the shape of the existing pipe. The liner is then cured in place, creating a new, seamless pipe within the old one.

Should there be standing water in my sewer line?
No, there should not be standing water in your sewer line. Sewer lines are designed to carry waste water and solids away from your home and into the municipal sewer system or septic tank. If water is standing in your sewer line, it may be an indication of a blockage or other issue that needs to be addressed.

Standing water in your sewer line can cause a number of problems, including slow drains, backups, and unpleasant odors. It can also attract insects and other pests, creating a health hazard for you and your family.

If you notice standing water in your sewer line, it's important to have it inspected as soon as possible. We can identify the cause of the problem and recommend a solution, which may involve clearing the blockage or repairing the damaged pipe.

Ignoring standing water in your sewer line can lead to more serious problems down the line, so it's important to address the issue as soon as possible.

How long does it take to reline sewer pipe?
The time it takes to reline a sewer pipe can vary depending on the size of the pipe, the extent of the damage, and other factors. In general, relining a sewer pipe can take anywhere from a few hours to a full day.

The process of relining a sewer pipe involves several steps. First, one of our plumbers will inspect the pipe using a camera to identify the location and extent of the damage. Next, the plumber will clean the inside of the pipe using high-pressure water or another cleaning method.

Once the pipe is clean, the plumber will insert a flexible liner into the existing pipe and inflate it to mold it to the shape of the existing pipe. The liner is then cured in place using hot water or steam. The curing process can take several hours to complete, depending on the type of liner and the curing method used.

After the liner has cured, the plumber will use a camera to inspect the newly lined pipe to ensure that the lining is secure and free of defects.

Overall, relining a sewer pipe is typically faster than traditional pipe replacement methods, which can take several days or even weeks to complete. However, the time it takes to reline a sewer pipe can vary depending on the specific circumstances of the job.
